Armstrong number

A number is said to be Armstrong if the sum of the cubes of its digits is equal to the original number.

Example : N = 153  ,   1³ + 5³ + 3³ = 153    // 407 is an Armstrong no.

import java.util.*;

class Armstrong

{

    public static void main(String args[])

    {

        int  s = 0 ,   rem   ;

        Scanner sk = new Scanner(System.in) ;

        System.out.print("Enter ur number : ") ;

        int n = sk.nextInt() ;

       

        int temp = n ; 

           

        while(n!=0)

        {

            rem = n % 10 ;

            s = s + rem * rem * rem;

            n = n / 10 ;

        }        

        if(temp  ==  s)

        {

            System.out.println(" The given number is Armstrong ");    

        }       

         else

        {

            System.out.println(" The given number is Not Armstrong ");    

        }       

    }

}

==================================================================

An Armstrong Number, the sum of power of individual digits is equal to number itself.

 For example 0, 1, 153, 370, 371 and 407 etc are the Armstrong numbers. That is  :

153=1*1*1 + 5*5*5 + 3*3*3

or

1634 = 1*1*1*1 + 6*6*6*6 + 3*3*3*3 + 4*4*4*4

WAP to prove that the sum of cubes of the digits is equal to the given number.

class  Armstrong

{

    public static void main(String args[])

    {

       int num = 1634 ;

       int t1 = num , len=0 ;

      

       while(t1 != 0)

       {

            len = len + 1 ;

            t1 = t1 / 10 ;        

       }

      

       int t2=num , arm=0 ;

      

       while(t2 != 0)

       {

            int mult = 1 ;

            int rem = t2 % 10 ;

           

            for(int i=1 ; i<=len ; i++)

            {

                mult = mult * rem ;

            }

           

            arm = arm + mult ;

            t2 = t2/10 ;

       }

                      

        if(arm==num)

        {

            System.out.println(" The given number is Armstrong ");    

        }

       

         else

        {

            System.out.println(" The given number is NOT an Armstrong ");    

        }

       

    }

}
